Hi Angus,
The library is very good but I am just not using it for the sake of the functionality that U8glib is providing.
I need the API like this :
void drawBitmapP(u8g_uint_t x, u8g_uint_t y, u8g_uint_t cnt, u8g_uint_t h, const u8g_pgm_uint8_t *bitmap)

u8g : Pointer to the u8g structure (C interface only).
x: X-position (left position of the bitmap).
y: Y-position (upper position of the bitmap).
cnt: Number of bytes of the bitmap in horizontal direction. The width of the bitmap is cnt*8.
h: Height of the bitmap.
bitmap is an array which light up the pixels where 1 is there as an bit and if 0 then that bit is black.
It would be just wonderful, if you could provide us this API.
